Questions & Answers

Do UV water purifiers really work?

UV water sterilizers are believed to provide the best remedy for removing biological contaminants from drinking water. Ultraviolet water treatment systems work by emitting UV lights from various sources, such as the sun. These UV lights discharge beams of radiation that are meant to eradicate bacteria and other microorganisms in water. While effective, the performance of these UV lights depend on how much intensity the system is able to emit. If water treatment systems are not able to produce high intensity UV lights, then the radiation will be insufficient in killing the DNA of all existing bacteria and viruses in the water. These same UV lights also happen to be invisible to the naked eye, which makes it difficult to ascertain the condition of the UV system. This commonly leads to water treatment companies unwittingly using defective UV systems for long duration’s. For this reason, Pure Aqua engineers recommend substituting the lamp in your UV water treatment system at least once a year.

Does UV light kill bacteria in water?

Yes, the essential function of UV lights is to wipe out biological contaminants such as bacteria and viruses. However, it is ineffective in targeting other contaminants such as chlorine, salts, heavy metals, and etc. UV also fails in altering the water’s chemistry.  

Why UV treated water is not harmful for drinking?

No, UV water purification systems are designed to make drinking water safe by eradicating harmful contaminants from untreated water. They are best used alongside other water filtration systems, such as reverse osmosis, to effectively remove all types of contaminants.

Can UV light sterilize water?

UV light sterilizers are designed to do just that; sterilize water, swiftly and conclusively. They operate constantly to guarantee your water is purified to a clean extent. However, for the sterilization process to work effectively, the water must be purified before entering the system, and not contain any wastes or debris.

How does UV light clean water?

UV water purification systems disinfects living microorganisms by exposing them to ultraviolet lights. However, they do not filter them out of the water, nor do they remove other harmful contaminants. At the same time, water filters, such as reverse osmosis systems do not eradicate bacteria and viruses as well as UV light sterilizers. Ultraviolet sterilizers are required to work in conjunction with water filtration systems in order to produce clean drinking water.

Do UV Water Treatment Systems require regular maintenance?

Yes, UV water treatment systems will need periodic maintenance. Fortunately, UV systems are generally basic and straightforward to understand. Here are some aspects to observe to ensure your UV purification system will continue performing optimally for years to come:

  • UV lamps are the foundation of UV water purification systems, and must be substituted at least once a year. This is due to the UV lamps gradual reduction in light wave intensity by more than 50% of what a fresh lamp produces. If you happen to turn your UV lamp on and off more that twice a day, then the lifespan of the lamp will shorten even faster.

  • UV sleeves are used to protect the UV light lamp and must be changed at least once every couple of years. Since the water running through UV light systems carry debris, sediments, and other minerals, the UV sleeves are left vulnerable to being congested by these materials. If this occurs, then the UV sleeves will begin to impede the UV lights from piercing through the sleeve and water.

Commercial UV Sterilizers UVC

Pure Aqua’s UVC systems virtually eliminate microbiological contaminants without using potentially hazardous chemicals. Water enters through the bottom port of the ultraviolet generator cell and swirls around a low pressure mercury vapor lamp, which emits powerful ultraviolet light energy at 235.7nm wave length. Bacteria, viruses and other micro-organisms absorb the light energy which disrupts their DNA, and are destroyed safely inside a factory tested stainless steel cell. The treated water then exits through the top port of the cell and is ready for consumption.

Benefits and Advantages of Commercial UV Sterilizers UVC:

  • Effective: Virtually all microorganisms are susceptible to UV disinfection

  • Automatic: Continuous or intermittent disinfection without special attention

  • Fast: Water is ready for consumption as soon as it leaves the cel

  • Easy: Simple installation and maintenance. Minimum space requirements

  • Safe: No danger or way of overdosing, no addition of hazardous chemicals

  • Economical: Hundreds of gallons of water can be purified for a few cents per day

  • No Chemicals: No chlorine taste or corrosion problems

How Effective are UV Sterilizers for Water Treatment?

UV water sterilizers are highly effective against all microbiological concerns, such as viruses and bacteria. Despite this, many microorganisms have greater resistance to UV light systems, which renders low-power UV sterilizers ineffective in eliminating these infectants. For this reason, we make sure to specifically design practicable UV water treatment systems to remove all unwanted microorganisms.

Pure Aqua actively engineers and manufactures thousands of commercial UV purification systems. Our engineering process is straightforward and designed to provide safe, and effective UV water sterilizers in quick fashion. This procedure allows for products that maintain regular, or irregular disinfection in the absence of significant attention or assessment. While our commercial UV systems require minimal maintenance, some types of upkeep are still necessary, such as:

Lamp Substitution

–   Unlike normal fluorescent lamps, Ultra Violet lamps do not sizzle out, and are instead solarized, which reduces heat energy by about 60% of a new lamp after one year of daily usage. For instance, new lamps can generate dosage levels over 55,000 µW-s/cm2. However, this level declines to about  30,000 µW-s/cm2, which is the minimum dosage required to adequately eliminate contaminants. When it falls below this level then it is time to replace the UV lamp. Side note, if you have a habit of regularly switching the lamp on and off then the life of the lamp will be shortened dramatically.

No Overheating

–  As with the case with other lamp types, the ultraviolet lamp units our engineers utilize have no chance of overheating. Therefore, the need for acquiring supplementary equipment to address issues of overheating is erased.

Cleaning the quartz sleeve

–   Cleaning your UV system becomes a necessity to prevent the accumulation of dirt around the quartz sleeve. Unclean ultraviolet sterilizers will inevitably lead to impassable quartz sleeves, and effectively hinder the UV rays from passing through the sleeve and into the water. To preserve sufficient purity, glass throughout the lamp must be cleaned on a regular basis. The frequency of cleaning is based on the quality of the water and will be advised to install a pretreatment such as media or cartridge filters.


Tracking Ultra Violet Dosage

–  Meters are used to ascertain the intensity of the UV light, and the degree of which the radiation is passing through the quartz sleeve. If the UV dosage is found to be too low then the disinfection process will be ineffective. It is also useful in specifying when the time for cleaning the quartz sleeve and replacing the UV lamp.

Questions & Answers

Should I filter my water before UV light disinfection?

–   Filtering water before entering it into a UV purification system is crucial since the clearer water increases the UV transmittance ratio. This means that the UV system will be able to transmit light waves with higher energy, which will penetrate the water more effectively and sterilize it. Consequently, it’s of utmost importance to monitor your UVT and observe its levels to keep it over the manufacturer’s minimum requirement for effective disinfection.

How to select the right UV system?

–   Every UV light system has pretreatment requirements, such as a certain level of turbidity, iron, hardness, and ultraviolet transmittance (UVT). Unclear water will result in a low ultraviolet transmittance, which reduces the effectiveness of disinfection, since the water will be less able to transmit ultraviolet light. To compensate for this issue, you will need a larger UV system with a higher flow rate. However, if your water is perfectly clear then the UVT percentage should be just fine.
